Application

185MP is a high dispersion, high purity precipitated silica. It can significantly improve the wear resistance of the rubber compound, resistant to flexion performance, heating oxidation, instead of a large number of carbon black for high-performance tires, which can effectively reduce tire rolling resistance and reduce fuel dosage and improve the wet skid resistance and safety performance.
185MP mainly used in low rolling resistance of Passenger car tires, winter tires, and other applications.
